Scan of genomes for inherited variants lays bare new autism candidate
Lowered expression of a gene called DDHD2 may increase a person’s likelihood of having autism, according to a new analysis.
Lowered expression of a gene called DDHD2 may increase a person’s likelihood of having autism, according to a new analysis.
Two new analyses help to explain why mutations to the chromosomal region 16p11.2 can lead to autism, intellectual disability or language difficulties.
A trove of DNA sequences from 141,456 people — and counting — offers an unparalleled look at genetic variation.
Individuals with mutations in an autism gene called TRIO may have a range of conditions, including intellectual disability and anomalous head size.
The number of top autism genes has risen from 65 to 102, based on an analysis of more than 35,000 sequences. And researchers are seeing the first hints of autism risk variants in the regions between genes.
People with attention deficit hyperactivity disorder may carry certain rare, harmful mutations in many of the same genes as people with autism.
The largest analysis of sequences from autistic people and their families implicates 184 genes in the condition — nearly doubling the previous estimate.
An analysis of genetic sequences from nearly 500 people with autism and their relatives has linked 13 new genes to the condition. It has also uncovered a genetic cause for autism in about 10 percent of the autistic participants.
A new analysis challenges the idea that mutations in the sperm of older fathers lead to higher rates of autism among their children.
Spontaneous mutations that occur between genes may be as important in autism as those within genes.
